To all whom t meg/concern:

Be it known that l, GEORGE H. li"E\RaIs,of1V

Brooklyn, KingsV county, and State of New York, have invented certainnew and useful Improvements in Lamp-Stoves, ofwhichthe following is aspecification.; i

These improvements areV embodied in a lamp-stove, wherein isa cast-metalbase-piece connected by a hinge or articulation with the lamp-reservoir,and provided with legs for resting thereon, flues erected on thebase-piece and supporting a combustion-chamber, which is closed savewhere it affords ingress and egress f'or the products of combustion,aand a bolt securing the base-piece, fines, and combustion -chambentogether, whereby a very strong, economical, and otherwise superiorarticle is produced.

The accompanying drawing .illustrates an oil-lamp stove embodying myimprovements. Figure l is a central vertical section of such stove, andFig. 2 is a plan thereof.

Similar letters of' reference designate correspending parts in bothfigures.

-A designates an oil-reservoir, shown as of cylindrical form, and may beerected on legs or feet a. It is provided with lamps consisting ofwick-tubes B, wick-adjusting mechanism, and inclosing-shell b. It isalso provided with a mouth or orifice, G, and is shown as being soconstructed that its upper part may serve as a water-chamber, D. Edesignates a base-piece,which may,with advantage, be made of' castmetal, and is provided with the part c of a hinge, c c', connecting itto the oil-res; ervoir A, and with legs d, adapted tov-rest upon the topedge of the said oil-reservoir, or of that part which forms thewater-chamber D. Between the oil-reservoir and its appurtenances and thebase-piece E ample provision f'or the passage of' air to the lamps isafforded. Air-distributers G, consisting ofl a plate of foraminated orreticulated material supported upon the lamp wick-tubes immediatelyunder the base-piece E,and bracingand strengthening them laterally, orin lieu thereof, or in addition thereto, air-distributers H, consistingof cylinders or shells of foraminated or reticulated materialsurrounding the lamp wick-tubes, may be employed.-`v I designates thedeiectors,

which, as represented, are embodied in thev extinguishing the flame.

base-piece E, and may, with advantage, be so constructed, because thenprovision will be a'orded, whenl the base-piece is 'swung back, fortrimming and lighting the wick as well as J designates fines, (hereshown as two in number,) supported on the base-piece E over thedeflectors, and extending upward therefrom, so as to induce properdrafts of air to insure a perfect combustion of' oil in the lamps. Kdesignates a combustion-chamber, which is represented as made of' castmetal,l and is entirely closed save where it aifords ingress and egressfor the products of combustion ascending from the lamps; in other words,it is destitute of' any openings whatsoever except those through whichit communicates with the lamps, and that at which it receives thearticles to be heated. As here represented, it is supported solely bythe iiues J, and communicates directly therewith, wherefore it isisolated from the lamps. I have indicated by dotted lines K that it maybe of any desirable depth. It is preferably provided at the top edgewith a series of' projections, e, for supporting articles which arelarger than it in diameter, so that provision will be afforded fortheescape of the products of combustion below them, and it is alsopreferably provided with other projeetions, f, for supporting smallerarticles, so that they will not interfere with the escape of theproducts of combustion.

I have shown the iiues J as fitting tightly outside portions or liangesg g of' the basepiece E and combustion-chamber K, so that lap-joints areformed, and all these parts are braced laterally1 together, so as to berendered very strong and stable. A bolt, L, passing through thebase-piece and the combustionchamber, fastens them together with theflues between them, and form one rigid structure, which may be swungback at pleasure to afford facility for lighting, trimming,extinguishing, and replenishing the lamps.

The isolated closed combustion -chamber supported by the closed iiuespossesses great advantages. The lines, by confining the products of'combustion, induce strong drafts of air to the lamps and invigorate thecombustion, while the combustion-chamber allows them to expand in volumeand circulate slowly therein about the bottom of the article to beheated, so as to be most available, and then to pass upward around thesides of the article to be heated, wherefore they are most thoroughlyutilized.

As I dispense with a drum in this stove I produce a very cheap andextremely strong and durable article, wherein great economy of oil isattained, and with so perfect a combustion that the emission of noxiousvapors is obviated.

To render the stove more convenient it may be constructed so that it canbe lighted without altering its position, and may be provided withdevices capable of being moved wholly over the lamps to extinguish them,or partly over them, so as to reduce the size of the llames and the heatarising therefrom, without turning down the Wick, impairing combustion,and entailing the emission of vapors.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination, in a lamp-stove, of a base-piece, E, with legs d andhinge c, supported on a lamp, and a combustion-chamber adapted tosupport articles to be heated, with iues interposed between thebase-piece and the combustion-chamber, substantially as described.

2. In a lamp-stove, a cast-metal bottom piece, E, provided with part ofa hinge or articulation, and legs d, adapted to be supported on thelamp-reservoir, and to support the flues of the stove, substantially asset forth.

3. The combination of the base-piece E, provided with legs d and hingec, iiange g thereof, iues J, combustionchamber K, flanges g thereof, andbolt L, substantially as and for the purpose set forth.
